Abstract

PURPOSE:To obtain a timer having high accuracy, by continuously carrying out the timer survice to a timer which stores the next address in case the timer service time exceeds the duration of the clock pulse cycle to the timer. CONSTITUTION:A timer arithmetic control circuit CC, a reversible counter RVC and a detecting circuit PD form a multi-timer device. The circuit CC starts its operation at a moment when the logic of the status signal changes from 0 to 1 on a signal line 8, and continues the timer service while the logic is kept at 1. At the same time, a command pulse is delivered with every end of the timer service, and the numerical value 1 is subtracted from the count value of the counter RVC. The clock pulses supplied form a signal line 1 are added together by the counter RVC.
